So this should be a simple question. What do you guys do when you run across concave sections on the back when chasing a growth ring? I'm chasing one on the honey locust I got from spring buck, but there are spots where my draknife can't reach without violating into the sides since they are higher than the middle. I'm thinking I might try chisels to work those spots down but wanted to check with all you first. I haven't followed that many growth rings yet. I've just done board bows, or simply took the bark off.
